Do tennis strings have a shelf life? I've purchased some cheap strings on **** (reel for 30 bucks gamma advantage).. and i realized after playing with it that string quality is a factor... googled this string and not much information showed up but someone posted this string on this forum and was 2006... So i'm wondering if this string is that old then what are shelf life of strings usually..? It seemed like fresh new strings when opening it.. but looks can be deceiving. I'm wondering if i should buy any tennis strings off **** now cause who knows how long or environment they have been in..
